Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Pieces for Developers

  • Requires installing and running a background desktop app rather than being purely cloud-based.
  • Free tier trial of Pro features requires a credit card and reverts after 7 days.
  • Local-first storage means memory is not automatically synced across multiple machines without Enterprise controls.
  • Effectiveness depends on the breadth of integrations enabled, which adds setup overhead.

PubNub

  • Free plan storage history is limited to 7 days, which is short for apps needing longer message retention.
  • MAU-based pricing means costs scale directly with user growth, which can be less predictable than flat message-based pricing.
  • Pro-tier custom pricing above 50,000 MAU requires contacting sales rather than self-serve checkout.
